When I try to move a picture to another folder, the mouse symbol becomes a no parking sign and the move is unable.
Here is a picture showing all the context (XnViewMP 0.53, Win64, and the problem).

Did I miss something, or is it a bug ?
Something else : when writing in the forum I want to add an attachment, if I click on the button "Browse..." (in french "Parcourir...") placed below the writing field, nothing happens. So I can't add descriptive pictures and I must send pictures to another website then place here an external link. It's really annoying. Is it a problem only occuring for me or is it really a disabled function ?
And it's not all : It seems also that the BBCode tag img doesn't work as you can see above, although it is available in the buttons above the writing field.
